WEIGHING APPARATUS.

Application filed September 11, 1906, Serial No. 334,180. Renewed August19,1907. Serial N6. 389,260.

BAcii, a citizen of the United States, residing at Savannah, in thecounty of Chatham and State of Georgia, have invented new and useful Imrovements in Vveighing Apparatus, of wine the followingis-aspecification.

This invention-relates to weighing appa ratus of the same general typeas that set forth in Letters Patent No; 791,342 granted to me on May 30,.1905, and to which refer- "ence may be had.

The present application covers certain matters disclosed but not claimedin an application for patent entitled weighing andcan fillin apparatus,filed April 11, 1905, and Seria No. 311,157.

The present invention relates particularly to a simple and effectiveineans forsupplying the-buc et of .the weighing machine with a stream ofmaterial to make up the load there-- in, and for quickly and accuratelycutting off said stream for which purpose, as will hereinafterap ear,one or a p urality of valves 111%17611131 'zed.

hile I have designated the invention as j weighing apparatus sonre .ofthe features thereof may be utilized in machines' where weighing is notactually done.

In the drawings accompanying. and forming a part of this specification,I show in detail certain forms of embodiment of the invention, which, toenable those skilled in the art to practice said invention, will befully set forth in thefollowing description, while the novelty of saidinvention will be included 5' in the claims succeeding said description.

1 different scales, all larger than that upon which Fig. 1 is drawn.Fig. 7, which is also on a larger scale than Fi 1, shows in sectionalelevation a slight mo ification of the. feed controlling means. V

Like characters refer to In Fig. 1 of the drawin a weiglung a paratus\vhichinvolves the mechanism siown in the Letters Patent will not setforth in full the construction'and mode of operation of the partsrepresented herein and shown. in the Letters Patent, for, as will beunderstood, the invention lies principally in the means for supplying astream of material to the bucket o aweigheffectively controlling suchstream.-

. Referring now more particularly to'Fi the numeral 2 designates thebucket. io weighin machine; this bucket being-suspended end shown at theright in Fig. 1, which pro: jection' is provided with a pinJ9 for,aterment of-apawl 10 thereon with the teeth of ten tly rotativc shaft 13.

The i member 7 is moved forward:by'theengage-ig;

The framework of the machine carries a V. 60 gs I have shown freely. Theshaft of thi's'forcefeeder carries a sprocket wheel as 16 having africtional fit on the shaft of the feeder, which sprocket wheel isdriven by a'sprocket chain as 17 (see Fig. 1). Should the force feederencounter any obstruction in the hopper 1 1 no damage can result owingto the fact that the sprocket wheel 16 can turn on the force feedershaft. Under normal conditions the force feeder effectually loosens upthe material in the hopper and for this purpose is continuouslyoperable.

Upon the framework is ivotally mounted a latch 18 represented as eing ofthe gravitative t e and the toothed or workin end of whic1 when thereciprocatory member 7 has made its full advancing or working stroke isadapted to enter a notch 19 in said member 7 to prevent rebound thereof.On the intermittently rotative shaft 13 is carried an arm as 20 which isfound inthe. application and Letters-Patent to which reference has beenhereinbefore made. The plrimary purpose of this arm 20 is to return 1; ememl er 7 to its initial function is pe ormed the free end of the arm 20strikes the latch 18 and disen ages the same from said part 7, wherebythe atter can 21 for de ivering material directly into the bucket 2 andmovable across the bottom of the hopper 14 and necessarily across thetop of this spout 21 is a valve 22. The valve, therefore, is of thesliding type,it being shown as made in the form of a plate provided withan outwardl extending and elongated stem 23 guide for longitudinalmovement by a bracket'as 24 fastened to the ho per 14. 0

On t e stem 23'at some convenient place thereof are two projections 24and 25 which ma consist of collars adjustable longitudinaly of said stem23. These two adjustable collars are ordinarily made-in the form ofnuts, the stem 23 between them ,being straddled by the forked end 26 ofa lever 27 loosely supported between its ends by the shaft 28, saidshaft being sustained by the framework of the machine in any suitableway. hen the lever 27 strikes against the collar- 24 the valve 22 willbe closed, while when said lever strikes against the collar 25 saidvalve will be opened. ,The valve as will hereinafter appear has twodistinct and separate stages of operation, it being moved from its wideopen position during which the ,maximum stream flows into the bucket 2to osition and just before. this ing afterwards discharged and theseseveral operations are secured by power, the parts being-so timed intheir actions as to properly as at 30, the lateral projection 31 on thele-.

ver 27 being disposed between the branches of said bifurcation and beingalternatelyen-v gageable by the projections 32 and 33 on said branches,thes projections being ad-' justable and consisting. preferably ofscrews tapped through the said branches. The

screw 32 engages the projections 31 in a di-'- rection to impart to thevalve 22 throu h the intermediate mechanism its primary c osing movementwhile, the screw 33 by engagingsaid projection 31 opens said valve 22through said intermediate mechanism.

There is shown as fastened to the shaft 28 and as depending therefroman' arm 34 .to which is jointed the forward end of the link 35, the rearendof said link being similarly connected to the angle lever 36 suported by the framework of the machine and in one direction by the cam 37on the intermittently rotative shaft 13. Said angle levelis shown asoperated in opposition cam 37'by a spring 38.

\ There is a secondary actuator for the lever to the operable 27 and thesame may consistofa part'as 39 represented as consisting of an L-shapedlever piv'otally supported between the endsof its vertical arm upon theforward extension 40 of the downward projection 8. The hori-' zontal armof this actuator 39 is equipped' i'ni41 engageable against the lowerwith .8. arm of t e lever 27 for swinging said lever 27 in such way asto give the valve 22 its. final closing movement. This actuator 39 isyieldingly mounted so. as to avoid injury to any of the arts should the,valve 22 be blocked accir entally. in closing.

this result a coiled spring as 42 may be inter To secure posed betweenthe upper end of the actuator 39 and the downward projection 8, all asshown clearly in Fig. 2. a

When the member 7 is moved forward, the bucket 2 atthis time being inposition to and reeeivin r the full volume of the supply stream om thehopper 14, the shaft 13 is thrown in action, al as set forth in Letters-Patent hereinbefore referred to and during 5 the rotation of said shaft13 the cam 37 wil operate the angle lever 26 in a direction to thrustthe link 35 to the right in Fig. 1.

The

arm 34 is moved in a correspondin direction while the arm 29 is moved tothe eft in said Fig. 1 so as to carry the screw 32 against theprojection 31 for rocking the u per arm of the lever 27 to the left insaid 1g. 1. The

upper end of the lever 27 will on this motion 15 lars 24 and 25.

en age the collar 24, and thereby move the va ve 22 to its "dripposition as also shown in said Fig. I to 1permit a reduced or dripstream to flow into t e bucket 2. When the load in 5 saidbucket iscompleted the member 7 will have reached the limit of its forward motionandfijust before this takes fplace the pin 41,

strikes the lower branch-"o the lever 27 so that the valve 22 can by thelever 27 strikingthe collar 24 be given its final closing move- .ment;The parts are so timed as to secure the 0 erations outlined and there islost motion iietweenthe actuator 29 andlever 27 .and between said lever27 and the two coltionfmay be adjusted bymeans of the screws 32 and33and collars 24 and 25 so as to se cure with'precision the action of thevalve 22. The opening of the valve 22 is secured rimarilfy' by thespring 38, which spring w en the lever-36 is under the action of thecam- 37 .is tension'ed so. that when the lever 36 is releasedby thecam"37 the lever can be re- ,turx-ied tolits original position and onsuch movement the rod or link'35 is drawn to the left inFig. 1, the 'arm34 being correspondingly moved so as to actuate the actuator 29 whichinturn' swin s the lever 27 in a direc- 'tion to move the va ve 22 toit's open position.

The lever 27 for this purpose acts against the I IniFigs. 5 and 6 I showa construction whereinthere are two valves, one valve as 22 here"inbefored'escribed, and a second valve 22.

Those arts which appear in Figs. 5 and 6 and which have beenhereinbefore described will "be: given corresplonding characters. InFig.5, for example:v show the actuators 29 and 39, the lever 27, the arm34, link 35,

' 40 valve stem 23 and adjustable collars 24 and .25. The shaft 28 hasfixed thereto the arm 45, to the u er end of which is connected one endof a ink 46, the opposite end of said link being pivoted to the lowerarm of a lever 47 fulcru'med between its ends upon a bracket 48 onthe hoper 14, the upper end of said lever 47 bein a apted to' alternatelyengage the adjustable co lars 24 and 25 upon the stem. 23 of the'valve22. When the link 35 is ad- 50 vanc ed the two valves 22 and 22' aremoved toward each other through the intermediate position shown in'Fig.5. Upon p h b the rni'movement of said link, 35 the two valves illfbfmpletes its advancing motion "simultaneous closing toward ofi th etwovalves 22 and 22" the l'riot have completed its forward space betweenthe discharge edges or ,t e two valves. This reduced stream is cut bythe action of the valve 22, which action The amount of this lost mo-.

simultaneously opened; When? is caused by the art 39 striking againstthelower arm of the ever 27 which acts against said valve 22 ashereinbefore fully described. The valves 22 and 22 operate insuperposed; planes, b reason of which the discharge end of the va 've 22when closed may overlap the corresponding end of the valve 22 toeffectually cut off the delivery, of material from the hopper 14. Theform of invention illust'rated in Figs. 5 and 6 is adapted especiallyfor controlling streams of-largevolume.

The loads of material discharged from the bucket 2 enter a hopper as 50'for delivery thereby into cans as 51 movable along a way as 52 byconveying mechanism including in its construction slats as '53.

The hopper 50 and the actuating means therefor constitute no part of thepresent invention, but are claimedin the/applicationto which I havehereinbe'fore referred.

Thehopper 50 is mounted for rising and falling motion, it being thrustdownward by a spring 11.5155 bearing against a bracket as,

56 connected with the hopper and surround ing the u )wardly extendingrod 57, the upper end of w iich is provided with a cross piece 58 toengage the forward end of the beam- 3 to prevent the premature droppingof said end. When the hopper 50- is lowered b the action of .the spring55, the part 58'wi fall away from the forward end oi the beam 3 andpermit full and complete downward movement thereof. The ho per 50 isnormally held up by one arm 0 an angle lever 59, the other arm of whichis operable by the cam 60 on the shaft 13. When the cam has made acertain amount of movement on the rotation of the shaft 13, thehorizontal armoi the angle lever 59 falls away from the lower end of therod 57 and ermits the lowering of the hopper 50. Tieconstruction justoutlined, ex(-.ept the u per end of the rod 57 which is provided wit 1the cross piece 58, is fully set forth and illustrated, in theapplication No. 31-1 ,157 to which I have hcreinbefore referred, and initself forms no part of the present invention, for which reason a mored'etailm-l description thereof is not necessary.
